The main difference between Coralogix, SigNoz, and CubeAPM is how they manage telemetry data, deployment flexibility, and long-term observability costs.
Coralogix centers on log analytics and operates mostly as a SaaS model, while SigNoz delivers an open-source, ClickHouse-based observability stack built around OpenTelemetry. But CubeAPM offers complete MELT coverage (Metrics, Events, Logs, Traces) with smart sampling, on-premise/self-host options, and predictable pricing.
As observability costs rise and data localization requirements tighten, teams are moving away from siloed tools toward unified OpenTelemetry-native platforms. The shift is more about controlling egress, retention, and compliance while maintaining full-stack performance insights. CubeAPM bridges these priorities with full OTel observability and low-cost scalability.
In this article, we’ll compare Coralogix, SigNoz, and CubeAPM across telemetry coverage, deployment, pricing, sampling, and enterprise support to help you choose the right observability solution.

Coralogix vs SigNoz vs CubeAPM: Feature-by-Feature Breakdown
Each of these observability platforms brings a different approach to telemetry, cost control, and scalability. Below is a detailed breakdown across eight key dimensions — from OpenTelemetry support to pricing, retention, and real-world usability — to help you choose the right fit.
Telemetry Support (OTEL)
CubeAPM offers 100% OpenTelemetry-native support across all signals — metrics, events, logs, and traces. This allows engineering teams to instrument their applications and infrastructure seamlessly using existing OTEL SDKs and exporters. It supports automatic trace correlation across distributed services, databases, and frontend spans.
Coralogix, on the other hand, provides partial OTEL compatibility through custom SDKs and proprietary ingestion APIs. While it can ingest OTEL traces, full correlation across logs, metrics, and events still relies on Coralogix-specific agents. This creates some integration overhead, especially for teams using mixed toolchains.
SigNoz is open-source and OTEL-native by design, offering robust collector support for ingesting data directly into ClickHouse. However, integration flexibility is limited to its self-managed stack — meaning scalability and storage tuning must be handled manually by the user.
MELT Support
CubeAPM unifies Metrics, Events, Logs, and Traces (MELT) in a single dashboard, enabling complete context for performance, reliability, and user experience. This integration allows teams to correlate spikes in metrics directly with logs and traces, reducing Mean Time to Resolution (MTTR) and improving RCA accuracy. It also extends to RUM and synthetic monitoring for complete frontend-backend visibility.
Coralogix primarily focuses on logs and metrics, offering limited native tracing capabilities. Although it supports log-based metrics and anomaly detection, the absence of fully integrated trace-level data limits its use for distributed systems debugging.
SigNoz covers metrics, logs, and traces, but lacks a dedicated event-processing layer. While developers can visualize telemetry data effectively, cross-signal correlation is not as tightly coupled as CubeAPM’s unified pipeline. For deep dependency mapping or end-user tracing, CubeAPM delivers broader visibility.
Deployment (Self-host/On-prem)
CubeAPM provides the flexibility to deploy as on-premise or self-hosted on Kubernetes and VMs. Based on CubeAPM’s documentation, setup typically takes under an hour with out-of-the-box OTEL collectors and prebuilt dashboards. All data remains within the customer’s cloud, ensuring compliance with localization laws like GDPR, HIPAA, and India’s DPDP Act.
Coralogix operates mostly as a SaaS platform but with some components optionally hosted on-premises. While it aims to lower long-term storage cost, it still involves public egress charges, creating compliance gaps for certain industries.
SigNoz offers full self-hosting through Docker or Kubernetes, providing open control over your telemetry stack. However, this flexibility requires hands-on maintenance — managing ClickHouse clusters, retention policies, and scaling collectors. For large-scale environments, this adds considerable DevOps overhead compared to CubeAPM’s managed or hybrid deployment models.

While affordable for smaller setups, larger environments face predictable scaling costs and infrastructure management overhead.
In short, CubeAPM’s flat $0.15/GB ingestion pricing eliminates billing complexity, providing clear cost control and maximum scalability across all telemetry types.
Sampling Strategy
CubeAPM employs an advanced smart sampling engine that’s context-aware — meaning it retains high-latency, high-error traces and discards low-value noise. This approach reduces data volume while maintaining deep diagnostic insight. It’s particularly useful for large microservice environments or high-throughput applications where full data capture is impractical.
Coralogix and SigNoz both rely on probabilistic or tail-based sampling, which randomly selects traces without contextual awareness. While efficient for reducing load, it can omit critical traces that reveal the root cause of performance issues. In contrast, CubeAPM’s adaptive sampling improves observability precision and cuts storage cost by 60%+.
Data Retention
CubeAPM offers unlimited retention for logs, metrics, and traces at no additional charge, allowing engineering and compliance teams to perform long-term RCA or trend analysis. Data stays within the customer’s cloud, ensuring security and compliance. This makes it ideal for sectors like finance, healthcare, and government.
Coralogix uses an archival model where older logs are pushed to the customer’s cloud storage. While this lowers direct Coralogix storage bills, it still incurs data egress fees and introduces compliance challenges since the data first transits through Coralogix servers.
SigNoz retention depends entirely on ClickHouse storage allocation. While flexible, it means users must scale their infrastructure and manage compaction manually to prevent performance degradation. CubeAPM eliminates this overhead by offering automatic, compliance-ready retention policies.
Support Channel & Response Time
CubeAPM provides real-time support through Slack and WhatsApp directly with core engineers — most queries are resolved within minutes. This is a massive advantage for SRE and DevOps teams managing production workloads. Enterprise customers also get dedicated onboarding and alert setup assistance.
Coralogix offers traditional email/ticket-based support, with turnaround times ranging from hours to days, depending on the severity level. SigNoz relies on community Slack and email, with premium SLAs only available in its Cloud edition.
CubeAPM’s direct engineer-to-engineer support model drastically reduces downtime and accelerates incident resolution compared to ticket-based systems.
